Nay, even commenting is often pointless. HN likes to overly articulate drivel more often than not. Indeed, even this very comment is pointless, because what does it really add but another section in another chain of pointless drivel? Socializing is human. Any and all communication platforms like forums, or even Twitter, work to capitalize on the needless want to contribute something. Which is often unnecessary. I'd argue that lurking is often the smarter choice.
Not that books are exempt from the same problem. Many of them are pointless or suck too, but that's just part of living in a flawed world.
